In the 980s, former Later Han general Yang Ye pledges allegiance to Emperor Taizong of the Song dynasty. Yang leads his family and followers to defend Song from invaders of the Khitan Liao Dynasty. Having served Song for years, the Yangs are viewed as an honorable, courageous, and patriotic clan that protects the nation from foreign invasion.
Unfortunately, at the Battle of Golden Beach, the Yangs fall into a conspiracy trap, which concludes with the death of Yang Ye and four of his sons, and another son becoming a prisoner-of-war. Yang's last two surviving sons, Yang Yanzhao and Yang Yande, must continue their family's legacy to bring peace and prosperity to Song, in addition to seeking vengeance on the conspirators.
